Study On Costruction Technology Df The Prestressed Concrete Continuous T Beam’s Negative Moment Area

Prestressed concrete is to give concrete compressive pre stressexerted, to reduce or offset load caused by concrete tensile stress, thestructure of tensile stress control in a small range, even in the state ofcompression, to postpone the appearance and development of cracks ofconcrete, thereby improving the anti cracking performance ofcomponents and stiffness, can give full play to the characteristics,compressive strength of high strength material of high reduce, make thestructure of light.Prestressed concrete continuous beam bridge is better than that ofreinforced concrete continuous beam bridge across greater capacity, andit has the overload capacity, easy maintenance, expansion joints,deformation and advantages, rigidity, stable running, because of theconstruction unit of the quality responsibility and on-site technicalmanagement level and the actual operation team technical level uneven,prestressed concrete continuous T beam roof negative moment areaconstruction is easy to produce the amount of problems, only to ensurethat the negative moment tension grouting construction quality, in orderto effectively improve the overall stability and durability of the bridge,the bridge damage early prevention, improve the safety of bridge. The bearing red high-speed supervision contract2tiger Gou Bridgeand road bridge village, negative moment construction of tiger GouBridge and road bridge village from construction preparation to the dataprocessing phase to construction phase, the entire process involved inon-site way, through consulting mentor, referring to the standard andbooks and supervision office the mutual learning, project technologypersonnel and discussion, find out the key process to guarantee thequality of the project, to find and solve the problems in the constructionprocess, the project quality to achieve the qualified standard, assessed asexcellent engineering.
